COMPOSITION-APPLYING MECHANISM FOR MATCH MACHINES.

Application filed ctober'6,'1925. Serial No. 60,806.

This invention relates to compositionapplying mechanism for match makingmachines; having reference more especially to continuous machines formaking paper or cardboard strips of matches which are subsequentlysubdivided into match cards of proper size for use in the manufacture ofso-called book matches. Machines of this type include an endless carrierby means of which cards of staggered match splints are transportedthrough a match mal-:ing cycle, including a vat containing ignitiblecomposition, which composition is carried in a thin layer into the pathof the ends of the traveling splints by means of a transfer roll that ispartially immersed in the contents of the vat: The free ends of thesplints, with their bread faces disposed transversely of the pats oftravel, are moved tangentially of the roll and through the peripherallayer of composition on the latter. Such faces aretherefore wellsupplied with composition, but the thin edges of the splints, beingparallel with the direction of travel, are sparsely covered with thecomposition, thus resulting in the formation of imperfect match heads.

The objectof our invention is to overcome the defective operation abovementioned, and to that end we provide simple and eidcient mechanismwhereby the free ends of the splints are uniformly dipped in a layer ofmatch composition during the travel of the carrier, as will behereinafter described and claimed.

In the drawings- I Figure l is a side elevation of a portion of a matchmaking machine equipped with composition applying mechanism embodyingour invention.

Fig. 5 is a plan of the tank and the composition carrying apron therein.

Fig. 6 is a transverse vertical section through the tank, as on the line6-6. of Fig. 4.

Referring to the drawings, 10 designates a portion of the travelingendless carrier of a match making machine, which carrier comprises achain of links constructed to receive succeeding cards C of matchsplints and carry them in spaced relation to each other through thematch making path.

Removably supported beneaththe carrier and the depending cards ofsplints by means of a suitable platform 11, is a tank 12 which isadapted to contain match head composition in a liquid state. Thecomposition is conveniently supplied to the tank from an overhangingreservoir 13, the uniform level of the composition within the tank beingmaintained by usual devices.

Mounted upon suitably-disposed rollers 14:, 15 within the tank is anendless apron 16, rubber composition or other appropriate flexiblematerial, the upper horizontal run of which apron is adapted to travellongitu dinally of the tank and on or about the level of the containedcomposition. The width of the apron is somewhat greater than the lengthof a card of matchsplints, and the longitudinal. edges of the apron areprovided with upstanding beads or flanges 17 between which is affordedon the upper horizontal run of the apron a shallow channel the depth ofwhich is substantially that of a match head. Hence during the travel ofthe apron a thin layer of composition of suitable depth for theformation of match heads is carried continuously along the upper run ofthe apron.

The rollers 14:, 15 are mounted on trans verse shafts 18, 19 locatednear the respective ends of the tank. The roller 14 is fast on the shaft18 and the latter is journaled in bearings 20 at the sides of the tank,one end of the shaft extending outward and being operatively connectedwith a suitable source of power. In the present instance the shaft 18 isprovided with a gear 21 in mesh with a gear 22 on a shaft 23 which isconnected with and driven from a shaft of the match machine. Thus theroller 14 is continuously rotated and the apron 16 is impelled at theproper speed and in the proper direction,

1. e., the upper run of the apron, with the layer of compositionthereon, moves at the same speed and in the same direction as theadjacent portion of the match card carrier.

The roller 15 is loose on the shaft 19, and the latter has its hearingsin a pair of arms 24 that are pivoted, as at 25, to the respective sidewalls of the tank so as to permit the roller 15 and the proximateportion of the flexible apron to be swung upward and above the tank(when the tank is pulled outward) as occasion may require, as indicatedby dotted lines in Fig. 2.

Preferably suitably-disposed brackets 26,

27 on the inner sides of the tank serve as stops to support the arms intheir respective horizontal and raised positions.

Any suitable means may be used in connection with the tank 12 forheating the contained composition and keeping it in a liquid condition.In the present instance this is conveniently accomplished by arrangingthe usual steam-jacketed composition vat 28 in inverted position beneathone end of the tank, as seen in Figs, 1 and 2. i

j The match card carrier in a part of its travel is supported and guidedabove the tank by sectional rails borne by a vertically movable framestructure, which structure includes two pairs of parallel bars 29 thatextend longitudinally of the carrier and are jointed at their outer endsto suitable supports, as at 30, 31. The inner or meeting ends ofthesebars are jointed by a cross-shaft 32 equipped with antifrictionrolls 33, which rest upon a pair of sector cams 34. These cams, whichare mounted on studs 35 projecting from brackets on a pair of standards36, are simultaneously operable by suitable crank and link connections37 to lift or to permit the descent of the flexibly connected ends ofthe frame bars, thus correspondingly moving the sectional guide rails,the partof the carrier thereon and its depending cards of splints.

The carrier is raised and lowered, as just described, preparatory to thestop )ing and starting respectively of the mac aim, the mechanism forthis purpose being of known construction. Heretofore the carrier when indown position moved in a fixed path across the composition applyingroll, so as to advance the depending ends of the splints through thelayer of composition on the periphery of the roll. 0 According to ourinvention, however, the carrier when down travels in a path whicheffects the dipping of the splints into the layer of composition on theupper run of the apron, and thereafter gradually raises the splintsabove the composition and permits them to pass clear beyond the tank,the ascending portion of the carrier being vertically vibrated in amanner to dip the splint-s into and lift them from the layer ofcomposition, similar to manual dipping; thus insuring the formation ofuniform heads on the splints.

The rails which support and guide the carrier above the tank comprise ateach side of the tank, three succeeding sections 38, 39, 40'. Thesection 38 is supportedby brackets 41,

42 depending from the adjacent frame bar 29, the outer end of suchsection resting loosely on the bracket ail and the inner end of thesection being pivoted, as at &3, to the bracket 42. This section 38 isprovided adjacent the receiving end of the tank with a decline 44merging with a lower horizontal portion 45 of substantial length, andhence the portion of the carrier traveling on the section 38 is loweredand horizontally guided in a manner to dip the splints into, and advancethem for a. prolonged interval through the layer of composition on theapron. The second section 39 is pivoted at one end, as at 4:6, to thebracket 42 and thence normally inclines upwardly to the foot of a link4:7 to which it is pivoted at the other end, as at 48, so as graduallyto raise the portion of the carrier imposed thereon and thus lift theprogressing splints above the tank. The third section 40 is pivoted atone end, as at 49, to the foot of the link 47 and extends horizontallyin the normal plane of the rail to a depending frame bracket 50, towhich such section is pivoted, as at 51.

y The links 47 to which the sections 39, l0 at the respective sides ofthe machine are jointed are connected by means of straps to eccentrics52 fast on an upper transverse shaft 53 having its hearings in standards54; supported by the movable frame structure, and hence when theshaft 53is actuated the two pairs of rail sections 89, 40, together with theportion of the carrier borne thereby, are rapidly vibrated vertically,and in consequence the splints which depend from the lllll series ofcarrier links supported on the inclined rail sections 39, are moved downinto and up from the underlying layer of com position in a manner toeffect the described uniform dipping of the splints in the underlyinglayer of composition on the apron.

In the present instance the shaft 53 is equipped with a sprocket wheel55 which is connected by means of a chain 56 with a similar wheel 57 ona shaft 58 which is geared with and actuated by the driven shaft 23previously referred to.

From the foregoing it will be seen that our invention is characterizedby the provision of an endless flexible element mounted to travel withinand longitudinally of a composition-containing tank and having acontinuous shallow channel which affords in the upper run of the apronan elongated receiver and conveyer for a uniform horizontal layer ofcomposition into which the free ends of the splints borne by the carrierare effectually dipped in a manner closely approxi1nating the manualmethod of dipping matches; thereby insuring the formation of uniformheads on the match splints as previously mentioned.

It is to be understood that our invention is not limited to theparticular construction herein disclosed, as the mechanism may bemodified within the principle of the invention and the scope of theappended claims.
